Hey guys, NOOB here. I have a Definitive Technologies supercube I hooked to my Pioneer VSX-84TXSI Elite reciever. I bought my sub back in March and have loved it ever since, that is until last night. We were watching the new HULK movie and when the cannons were firing everything sounded great until about half way through the cannons. My sub started making a quick repetitive ticking noise through the speaker, even with the input wire disconnected it makes the noise. I pulled opened up the sub and inspected everything visually and couldn't see anything wrong or burnt. I hooked up my speaker directly to the receiver and it seemed to sound good (although it didn't have near the movement withuot the amp), but no ticking. I plugged the sub system back in without the speaker itself hooked up and the amp made a ticking noise at about half the speed as when the speaker is hooked up.
When I opened the housing to get to the internal amp I noticed some of the screws holding the amp in place had not been run all the way down against the mounting plate, so it was a little bit loose. I'm sure the vibration wasn't good for it. This was purchased brand new as an anniversary gift to me from my wife but when we contacted the seller he informed us he was not an "Authorized Dealer" so we can't get warranty.

I'm guessing the amp is bad, I'm considering bringing a sub out of my car that I am no longer using to hook up just to make sure it's not the speaker. Any thoughts?
Any, and all help is greatly appreciated.
